Sheryl Crow is now claiming that her toilet paper idea was a joke.The reaction to it should tell her something about the environmental movement. People thought it was a serious suggestion because they are used to hearing equally ludicrous things coming from environmentalists. Even The Daily Show took her at face value last night. Until green environmentalists square the circle of modern life with their concerns about it and their proposed statist solutions, they're going to face exactly the same problem. Her joke has almost certainly harmed the statist green cause, for which I am grateful to her. It also says something about how America views its celebrities. But that's a discussion for another place.
